Hi Prabhakar If you had given the code snippet it would have been much easier to reproduce the error. Anyway lets say you are using a button and trying to handle a button's click event. Protected Sub Button1_Click( ByVal Sender As Object  ByVal E As CommandEventArgs) To handle a button's click event CommandEventArgs should just be EventArgs. You can either handle the Command event or you can cast sender (in the click handler) to Button and then read the CommandArgument from that. Button btn1 = sender as Button ; if ( btn1 != null ) { // use btn1.CommandArgument here as you see fit. } Please keep me informed and mark it as an asnswer if it help you
